Description

  The present invention relates to a power-driven small boat mainly used as a fishing boat, a houseboat, a ferry, etc.

  In general, when enjoying boat fishing in the sea, lake, etc., aboard a small boat (fishing boat, etc.) equipped with an outboard motor, etc., and when you arrive at a desired point, you anchor and fish from the ship. And if the fish doesn't go up at that point, I move to another point and enjoy fishing.

  However, when fishing, the hull often shakes and becomes unstable due to waves and swells generated when wind blows or other ships pass nearby. For this reason, the passengers were not always happy and enjoyed fishing because they were anxious or seasick. Also, when boarding, disembarking or moving on the ship, the ship may shake and become unstable, and sometimes the balance may be lost and it may fall on the ship and get injured or fall into the water.

  Therefore, the same person as the present invention has previously developed a keel that can be moved up and down, a rotating plate driving device and the like that can be attached to the hull of a small ship to stabilize the ship as a solution to solve this problem.

  However, in the case of a small ship equipped with these devices, etc., the keel etc. will become resistance during navigation, reducing the propulsive force, making it difficult to navigate at high speed and it takes time to arrive at the destination, There was a problem that fuel cost was high due to consumption of a lot of fuel.

  The present invention was developed in view of the above points, and the object of the present invention is to stabilize the hull during navigation and to reduce the resistance during navigation to improve propulsion, It is an object of the present invention to provide a power-driven small ship that can reduce the consumption of water.

  In order to effectively achieve the above object, the present invention according to claim 1 is a propulsion stability comprising a long plate member arranged along the bottom of the ship bottom and a short plate member hinged to the tip of the long plate member. A plate, an angle adjusting means for adjusting an angle of the short plate member with respect to the long plate member, and an elevating means for moving the propulsion stabilization plate up and down, the elevating means being a long plate arranged along the bottom of the ship bottom This is a power-driven small ship having a structure that includes a link mechanism that simultaneously moves up and down a plurality of locations on both sides of a member and an operating means that operates the link mechanism.

  In the power-driven small ship of the present invention, the angle adjusting means is operated to raise the tip side of the short plate member to the bow side, and the lifting and lowering means is operated to lower the entire propulsion stabilizing plate to a position away from the ship bottom. During navigation, the propulsion stabilization plate is positioned underwater to stabilize the hull, and as the navigation proceeds, the bottom of the ship rises slightly from the water surface or the water surface, and the water hitting the front of the hull is between the bottom and the propulsion stabilization plate. Therefore, the wave-making resistance and frictional resistance received by the hull can be reduced, speeding up can be achieved, and fuel consumption can be reduced.

  In addition, the propulsion stabilizing plate having the long plate member can be moved up and down quickly and easily by the operating means while maintaining the horizontal level of the long plate member through the link mechanism, and the hull becomes unstable when the propulsion stabilizing plate is moved up and down. You can be on the ship with peace of mind.

  Also, when anchoring at sea, etc., the lifting and lowering means are operated to raise the entire propulsion stabilizer and place it near the bottom of the ship, reducing the swaying of the hull due to waves and stabilizing the hull. You can enjoy fishing and so on, and of course you can prevent seasickness.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 to 5 are views relating to a power-driven small boat according to the present invention. The power-driven small boat 1 shown in the figure includes a screw 2, a long plate member 3 and a short plate member 4 which are rotated by an engine or the like provided in the boat. A propulsion stabilizing plate 5, an angle adjusting means 6 (see FIG. 6) that can change the angle of the short plate member 4 with respect to the long plate member 3, and an elevation that can move the propulsion stabilizing plate 5 in the vertical direction. And at least means 7. Although not shown, it is preferable to synchronize the angle adjusting means 6 and the lifting means 7 with a control device so that the position of the propulsion stabilizing plate 5 from the ship bottom and the angle of the short plate member 4 are controlled. .

  The long plate member 3 and the short plate member 4 constituting the propulsion stabilizing plate 5 are made of synthetic resin (or metal) such as PC, and are the same rectangular plate members having different lengths. Further, the long plate member 3 is about ¾ of the length of the hull 8, and the lateral width is substantially the same as or slightly larger than the width of the hull 8. The long plate member 3 of the propulsion stabilizing plate 5 is attached to the hull 8 via the lifting means 7, and the rear end 3 a is located near the rear end 8 a of the hull 8 when it is located farthest from the bottom 14. (See FIG. 1).

  The short plate member 4 has a length that is half to 1/3 of the length from the tip 3b of the long plate member 3 to the end of the bow 8b, the horizontal width is the same as the horizontal width of the long plate member 3, and a plurality of hinges 9 is hinged to the distal end 3 b of the long plate member 3. The short plate member 4 can adjust the angle with respect to the long plate member 3 by moving the tip portion 4 a up and down by the angle adjusting means 6.

  In the illustrated example, the angle adjusting means 6 (see FIG. 5) includes a screw shaft 11, a worm gear wheel (not shown) that meshes with the screw shaft 11, a worm gear worm (not shown) that meshes with the wheel, A casing 12 that supports a worm gear, a drive device 13 that rotates a worm (not shown), a control device (not shown) that controls each drive device 13, and one end connected to the lower portion of the screw shaft 11 to connect the bow 8b It consists of a rope 16 such as a rope or a chain that hangs from the hole 10 opened in the nearby ship bottom 14 to the outside of the ship and has the other end connected to the tip 4a of the short plate member 4. The hole 10 is sealed with a rubber cylindrical member or the like so that the rope 16 can be moved up and down and water does not enter the ship. The angle adjusting means is not limited to the illustrated example as long as the angle of the short plate member 4 with respect to the long plate member 3 can be adjusted.

  By operating the worm gear by driving the drive device 13, the screw shaft 11 can be moved upward or downward, and the bow 8b side of the short plate member 4 can be moved upward or downward via the connecting cable 16. . The means for moving the screw shaft 11 up and down is not limited to the worm gear, and a rack is formed at the top of each screw shaft 11 and meshed with the rack, a drive device for rotating the pinion forward and backward, and this drive A configuration including a control device that controls the device may be used, and the design may be changed to other configurations.

  Next, ascending / descending means 7 (see FIGS. 1 and 2) for moving the propulsion stabilizing plate 5 up and down simultaneously at a plurality of positions on both side portions 3c of the long plate member 3 arranged along the bottom of the ship bottom 14 in the illustrated example. It comprises a link mechanism 15 that moves up and down and an operating means 17 that operates the link mechanism 15.

  The link mechanism 15 includes a support frame 18 that is fixed to the hull 8 (see FIG. 1), a plurality of pivot portions 19 (see FIGS. 2 and 3) that project laterally from the support frame 18, and each pivot portion 19. And a connecting frame 21 that connects the upper portion 20a of each hanging rod 20 in the same shape as the support frame 18.

  The support frame 18 is a rectangular pipe frame having a width approximately the same as the width of the hull 8 and having a length that is 2/3 of the length of the hull. It is fixed by a fixing tool (not shown).

  The pivot portion 19 (see FIG. 3) is a straight pipe member of about 10 to 15 cm, and is provided in the vicinity of the front and rear end portions on both sides of the support frame 18 and the middle portion so as to protrude horizontally. .

  The hanging rod 20 is a straight metal member, and the vicinity of the upper portion 20a is swingably attached to each of the pivotal support portions 19 via the locking tool 22.

  The connecting frame 21 is a metal frame having the same shape that is slightly larger than the above-described support frame 18, and is pivotally attached to the upper portion 20 a of each hanging rod 20 by a locking tool 26. Then, by moving the connecting frame 21 in the front-rear direction (the bow / stern direction), the suspension rods 20 can be simultaneously moved in the same direction (the bow direction or the stern direction) with the pivot portions 19 as fulcrums.

  Moreover, the lower part 20b of each above-mentioned hanging rod 20 is latched to the side edge 3c of the long plate member 3 of the propulsion stabilizing plate 5 via the latching tool 23 (see FIG. 3), and the propulsion stabilizing plate 5 moves in the front-rear direction (bow / stern direction) in conjunction with the front-rear direction (bow / stern direction) of each hanging rod 20. Then, when the upper part 20a of each suspension rod 20 moves in the backward direction (stern direction), the propulsion stabilizing plate 5 moves obliquely forward upward (close to the ship bottom) on the bow 8b side.

  The actuating means 17 (see FIGS. 1 and 2) includes a hydraulic cylinder 17a and a hydraulic pressure supply device (not shown) in this example, and is mounted on the bow 8b side of the hull 8. A rear portion 17b of the hydraulic cylinder 17a is The hull 8 is pivotally attached to the bow 8b side of the hull 8, and the tip 17d of the rod 17c is pivotally attached to the front frame 21a of the connecting frame 21 described above.

  In the power-driven small boat 1 having the above-described configuration, the rod 17c is normally extended outward from the hydraulic cylinder 17a (see FIG. 4). With this state of the rod 17c, the connecting frame 21 is pushed to the stern 8a side, and the upper portions 20a of the suspension rods 20 connected to the connecting frame 21 are also tilted to the stern 8a side with the pivotal portions 19 as fulcrums. By this operation, the lower portion 20b of each hanging rod 20 is pulled up obliquely upward in the forward direction (the bow 8b direction), and the propulsion stabilizing plate 5 pivotally attached to the lower portion 20b is pulled up horizontally toward the bottom 14 of the boat. It becomes.

  For example, when going to a desired sea area in order to enjoy boat fishing in the sea, the engine is driven and the ship is taken out from a port or a dock. In this case, the long plate member 3 of the propulsion stabilizing plate 5 is in a state of being pulled up horizontally toward the bottom 14 as described above. Further, the short plate member 4 of the propulsion stabilizing plate 5 is slightly lifted by the angle adjusting means 6 from the front end portion 4a side to the hull 8 side.

  After leaving the port and going out to the open sea, the hydraulic cylinder 17a is actuated to pull the rod 17c toward the hydraulic cylinder 17a and move the connecting frame 21 in the direction of the bow 8b (see FIG. 1). As a result, each suspension rod 20 pivotally attached to the support frame 18 via the pivot portion 19 and inclined toward the stern 8 a is also substantially perpendicular to the long plate member 3 of the propulsion stabilizing plate 5. Further, the propulsion stabilizing plate 5 pivotally attached to the lower portion 20b of each suspension rod 20 via the locking member 23 descends to the stern 8a side while maintaining the horizontal state of the long plate member 3, and the most from the bottom 14 of the boat. It will be in a distant position.

  By driving the power-driven small ship 1 in this way, the propulsion stabilizing plate 5 is submerged in the sea along the ship bottom 14, and the ship bottom 14 rises slightly from the water surface or the water surface along with the navigation. The seawater that hits passes between the ship bottom 14 and the propulsion stabilizer 5 together with the waves. Therefore, the wave-making resistance and frictional resistance received by the hull 8 are reduced, and the propulsion force can be prevented from being lowered and the vehicle can run at a high speed. Moreover, fuel consumption can be reduced. Further, the power-driven small boat 1 is stabilized by the propulsion stabilization plate 5 positioned below along the ship bottom 14.

  Further, the power-driven small boat 1 according to the present invention has the long plate member 3 of the propulsion stabilizing plate 5 or the periphery of the long plate member 3 and the short plate member 4, particularly at appropriate portions on both sides (see FIG. 6). The structure provided with the fender 24 may be sufficient. By providing the propulsion stabilizing plate 5 with the fender 24, it is possible to prevent the propulsion stabilizing plate 5 from being damaged or damaged even when coming into contact with a berth or when approaching another ship.
